Particularly, the bioactive peptide is manufactured by separating an alpha s1 casein from cDNA library of human mammary gland and expressing it in E.coli, wherein 6 of histidines are added to C terminal in order to easily purify alpha s1 casein. CONSTITUTION: A human alpha s1 casein is expressed in E.coli and purified. And then, recombinant human alpha s1 casein is decomposed into trypsin. Thereafter, ACE inhibitory peptide is separated by using high performance liquid chromatography(HPLC). Next, an amino acid sequence of the selected peptide is analysed and a molecular weight thereof is measured. Finally, an ACE inhibiting activation of peptide is analyzed quantitatively.
